According to Suárez, each of Aristotle’s four causes counts as a cause because it inflows being to another, and each has a proper influx. Several scholars regard Suárez’s account of the influx of the final cause as unsatisfactory. These interpreters overlook his identification of the influx of a cause with its causality, and his view that the causality of a cause is an entity, a res or a mode. I argue that, on Suárez’s view, the influx or causality of the final cause is a component of the mode of action, and that this account satisfies the demands of his influx theory of cause. I also uncover some unfamiliar elements of Suárez’s view of final causality: that it is simultaneous with efficient causality and that, wherever an end is a real cause of some effect, its causality is an intrinsic feature of the action by which that effect is produced.
